This paper attempts to quantify the significance of the domestic saving effort for investment rates in a group of 25 emerging economies over the 1985-2006 period using a varying-coefficients, error-correction model. The model is also used to empirically examine how that significance is influenced by the degree of openness, and by the regulatory fra...

This paper examines the dynamics of saving–investment relationship in a group of industrialized countries over the last three decades using a random coefficients error correction model. The model is also used to empirically test whether countries that are more open in terms of trade policy are also more open in terms of capital flows, that is, whet...

This study attempts to reassess the evidence on the degree of capital mobility and crowding out by applying a varying coefficients model to data on 19 OECD countries over the 1971–1999 period. Our period-specific results strongly support the crowding-out effect as well as the low capital mobility argument for this group of countries as a whole. How...

This study attempts to examine empirically the implications of the degree of openness for total and individual factor productivity growth in a group of 19 OECD countries over the last three decades. The study combines both time series and cross-sectional data. The model employed is a generalization of the commonly used, growth-accounting model base...

In this study, we examine the role played by fiscal policy in explaining the differences in economic growth rates of the nineteen OECD countries over the 1971-1999 period. We model the impact of government spending variables (which can be taken as indicators of the size of government) on economic growth via their impact on total factor productivity...

This study examines the role of government size in explaining the differences in economic growth rates of the 19 Organization for Economic Co-operation and Development (OECD) countries over the 1971–1999 period using a random coefficients model. Our results indicate that, on average, total factor productivity growth, as well as the productivity of...

Broadly speaking, three views about the macroeconomic implications of fiscal deficits can be identified. The traditional Keynesian argument, assuming chronic unemployment, states that fiscal deficits stabilize aggregate demand, increase private saving and foster investment and growth. The neoclassical view, assuming self-equilibration of the econom...

In this study we re-examine the role of export expansion in developing countries in a production function framework. However, our study goes beyond previous studies by not only using more recent data, but more importantly, by adopting a random coefficients model that can be viewed as a refinement of laws as stated by Pratt and Schlaifer. The random...

This paper examines the relative forecasting performance of published estimators proposed for a structural equation in a large system using Monte Carlo experiments with antithetic variates. The performances of the estimators are compared in terms of the accuracy of the within-sample as well as post-sample predictions for 10 structural equations by...

In the study, the aim is to re-assess the Feldstein and Bachetta (FB) model, using cross-country time series data for the G-7 countries. The re-assessment involves two major innovations. First, the authors make a more efficient use of the data than attempted by both FB and Summers. Second, the authors adopt a varying-coefficients approach which is...

This paper reports the results of a Monte Carlo experiment conducted to compare the small sample properties of selected feasible estimators of the seemingly unrelated regressions model with unequal numbers of observations and with non-normal disturbances. Our results indicate that the choice of estimator depends mainly on the size of the sample, th...

This paper extends the Feldstein-Horioka (1980), Feldstein (1983) and subsequent studies on the degree of capital mobility, by adopting a random coefficients model. This approach is more general in that it permits inter-country variations in the degree of credit mobility to arise due to the difference in size as well as in other institutional or st...

This study examines the role of size and R&D in explaining the rate of growth of firms by testing Gibrat's law. In particular, this paper extends earlier studies, by addressing this question: Do the size-growth relationships and the consequent size-distribution of firms depend on whether or not the firms are operating in R&D-intensive industries? T...

This study intends to shed light on the relative reliability of computed t-statistics (quasi-t-statistics) of some commonly used estimators for the regression model with autoregressive non-normal errors. Our Monte Carlo results indicate the overall reliability of such t-statistics for making inferences about the true values of the coefficient param...

This simulation study focuses on the relative small sample properties of some widely applied predictors in regression with AR(1) errors where there errors are allowed to follow normal and non-normal distributions. The conclusions are: all predictors considered are significantly unbiased; the relative performances of predictors, from the efficiency...
